Yokogawa EJX210A-EMS4G-919EN-WA13B1SW00-B/KU21/TX Flange Mounted Differential Pressure Level Transmitter
Product Overview
The Yokogawa EJX210A-EMS4G-919EN-WA13B1SW00-B/KU21/TX is a member of Yokogawa's flagship EJX-A series. It utilizes a single-crystal silicon resonant DPharp sensor and can be directly mounted on a tank flange for continuous measurement of liquid level, density, or interface. This model is factory-prepared for a specific range and material combination (EMS4G diaphragm / 919EN process connection / WA13B1SW00 housing and electrical interface / B coating / KU21 bracket / TX additional certification), making it ready for immediate use. It is widely suitable for demanding applications in the petroleum, chemical, pharmaceutical, power generation, and offshore platforms.
Key Advantages
• Ultra-high accuracy: ±0.075% of upper range limit, ensuring more reliable batch control and inventory management
• Long-term stability: ±0.1% of URL/1-year drift, significantly reducing calibration frequency
• Ultra-fast 120 ms response time captures rapid level changes and improves process safety
• 4–20 mA DC + HART 7 protocol, compatible with existing DCS/PLCs, supporting remote configuration and diagnostics
• Multi-sensor diagnostics: Real-time detection of impulse line blockage, diaphragm corrosion, or abnormal temperature, providing early warning
• Exida & TÜV SIL2/SIL3 safety certification, suitable for direct use in SIS systems
• Local LPS parameter setting: Zero/span adjustment can be performed directly on the meter without a handheld operator
• Modular structure, with optional BRAIN, FOUNDATION Fieldbus, and PROFIBUS PA protocols
